Hm, same here. I lost /bin/sleep several times.


Would you please describe the problem in more details?
What kernel version? What does "I lost /bin/sleep" mean?
Does it mean that:
1. /bin/sleep was truncated to 0 bytes, i.e. "ls -l /bin/sleep" shows  
something like
-rwxr-xr-x  1 root root 0 2005-04-20 18:32 /bin/sleep
2. /bin/sleep disappeared ("ls -l /bin" doesn't show this file)
3. /bin/sleep exists, but filled by zeros
etc...

Thanks,
Edward.

I have a little script
printing status messages to the screen, sleeping two seconds and print
again - you name it. The probability that /bin/sleep is accessed at the
same time the system crashes is quite high (this is _no_ write access,
the system is even mounted noatime).

How could pure execution of a file cause corruption of the file itself?
Any idea ?

Apart from that single file, I never had any serious problems with
reiser4 on three busy systems for years - fsck.reiser4 works like charme.
